Well, I think it is great that you rescued this poor horse. May God bless you for taking care of one of his creatures.
However, horses are big, slightly unpredictable, animals that can hurt you in a heartbeat if you aren't very careful and know a bit about what you are doing. Please, be careful. She might not hurt you on purpose, but you could still be injured.
She sounds like she needs a lot of quality bonding time. And good ground manners as soon as you can manage to get a halter on her. Being green/wild could make her really nervous and jumpy, but what you said also made me think of my blind gelding. If they have problems with their sight, they can be extra sensitive.
Time, attention, and ground manners are probably the most urgent things she needs besides groceries and a vet visit or a farrier. From your description, I wouldn't be surprized if she had never been trimmed or vaccinated. Just go slow and steady desensitizing her to everything from the halter to ropes (and bags and tarps and anything new) and work up to teaching her to lead and go with cues on movement in a round pen.
There are lots of well informed people on this forum that will probably chime in with advise for you. Best wishes for rehabilitating this horse.
